Reducing power consumption in cluster system of mutual standby type

Abstract

A cluster system of mutual standby type forms groups each composed of a job execution system and a job standby system for taking over the job when problems occur in the job execution system, and provides information processing devices each with a job execution system and a job standby system of different groups. The information processing devices each include: an upper limit value storage unit for storing a power upper limit value, a power control unit for controlling use of power by its own information processing device so as not to exceed the power upper limit value stored, and an upper limit value setting unit for causing the upper limit value storage unit to store a power upper limit value smaller than the maximum power consumption of its own information processing device when it is not necessary to take over the job of another information processing device.

Description

INCORPORATION BY REFERENCE[0001]The present application claims priority from Japanese Patent Application No. 2011-51101, filed on Mar. 9, 2011 in Japan, the disclosure of which is incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The present invention relates to cluster systems and, in particular, to techniques for reducing power consumption.BACKGROUND ART[0003]Cluster systems have realized a high availability when a plurality of information processing devices (server computers, for example) are connected on a network and problems occur in any of the information processing devices by letting other information processing devices take over and carry out the process which was being carried out by the information processing device in trouble. However, because cluster systems have a redundant configuration, compared with non-cluster systems, the power consumption is inclined to increase. Therefore, techniques for reducing the power consumption of cluster systems are i...

AI Technical Summary

Benefits of technology

This approach effectively reduces power consumption in cluster systems of the mutual standby type by controlling power usage and optimizing performance based on operational needs, thereby minimizing unnecessary energy expenditure and ensuring efficient job handling during failures.

Problems solved by technology

Cluster systems have realized a high availability when a plurality of information processing devices (server computers, for example) are connected on a network and problems occur in any of the information processing devices by letting other information processing devices take over and carry out the process which was being carried out by the information processing device in trouble.

However, because cluster systems have a redundant configuration, compared with non-cluster systems, the power consumption is inclined to increase.

Hence, the technique disclosed in the aforementioned Patent Document 1 is not applicable, and thus it is necessary to reduce the power consumption in normal operation by some other method.

However, at present, there have not been any effective techniques proposed therefor.
